Types

Type selection

If you want to create an element, but are unsure which type to use, answering these questions will help you select the device type:

On the first look, full virtualization seems to be the better choice as it allows more operating systems and does not limit operating system functionality. Container-based virtualization though, is a very light-weight solution that gives quick access to Linux machines and is much easier to handle than full virtualization. E.g. Container-based virtualization allows users to configure theroot password or the IP addresses of the interfaces. Additionally, full virtualization consumes a lot of resources on the testbed, so it should be avoided if it is not necessary.

Configuration

Templates and Disk Images

Each device uses its own private disk image. This can be used to store any data, except for Repy devices, where the image is a read-only script.

When preparing a device, the configured template will be used as the initial disk image. Templates are the main distinction of devices in the editor’s menu and can be configured in the respective configuration menu.
